+Mongoose is a network library for C/C++. 
+It implements event-driven
 non-blocking APIs for TCP, UDP, HTTP, WebSocket, MQTT.  It is designed for
 connecting devices and bringing them online. On the market since 2004, used by
 vast number of open source and commercial products - it even runs on the
 International Space Station!  Mongoose makes embedded network programming fast,
 robust, and easy. Features include:

- Cross-platform: works on Linux/UNIX, MacOS, Windows, Android, FreeRTOS, etc.
- Supported embedded architectures: ESP32, NRF52, STM32, NXP, and more
+- Cross-platform:
+  - works on Linux/UNIX, MacOS, Windows, Android
+  - works on STM32, NXP, ESP32, NRF52, TI, Microchip, and other
+  - write code once - and it'll work everywhere
+  - ideal for the unification of the network infrastructure code across company
 - Built-in protocols: plain TCP/UDP, HTTP, MQTT, Websocket
 - SSL/TLS support: mbedTLS, OpenSSL or custom (via API)
 - Asynchronous DNS resolver
 - Tiny static and run-time footprint
 - Source code is both ISO C and ISO C++ compliant
+- Very easy to integrate: just copy `mongoose.c` and `mongoose.h` files to your source tree. See
+  [exact steps](https://mongoose.ws/documentation/#2-minute-integration-guide)
 - Works with any network stack with socket API, like LwIP or FreeRTOS-Plus-TCP
- Very easy to integrate: just copy `mongoose.c` and `mongoose.h` files to your build tree
- Detailed [documentation](https://mongoose.ws/documentation/) and
-  [tutorials](https://mongoose.ws/tutorials/)
+- Provides a built-in TCP/IP stack with drivers for bare metal or RTOS systems
+   - A complete Web device dashboard
+  [bare metal example on Nucleo-F429ZI](examples/stm32/nucleo-f429zi-baremetal)
+  is only 6 files
+   - For comparison, a CubeIDE generated HTTP example is 400+ files
+- Detailed [user guide, API reference and tons of tutorials](https://mongoose.ws/documentation/) available

 # Security
@@ -69,30 +73,6 @@ We take security seriously:
  have specific security requirements and run independent security audits,
  of which we get notified and in case of any issue, act similar to (3).

-# Supplement software
-
-This software is often used together with Mongoose:
- [mjson](https://github.com/cesanta/mjson) - a JSON parser, emitter and
-  JSON-RPC engine. Used to implement
-  RESTful APIs that use JSON, or implement data exchange (e.g. over MQTT
-  or Websocket) that use JSON for data encapsulation
- [elk](https://github.com/cesanta/elk) - a tiny JavaScript engine.
-  Used to implement scripting support
-
-
-# Precompiled web server binary
-
-We have built a ready-to-go, precompiled web server executable application for
-Windows and Mac. It requires no installation and no configuration to start.
-Simply copy `mongoose.exe` to any directory you want to serve, and double-click
-on `mongoose.exe` to start it.  Mongoose will iconify to a system tray and
-start serving your directory to a local network. 
-
-It is a great tool for sharing your files, or for local web or game
-development. It has a unique feature - an ability to share your local files via
-a global URL.
-
-Visit [download page](https://mongoose.ws/) to try it out.

+Rules for creating a new example:

+- Makefile golden reference for desktop/server example: [http-server](http-server)
+- Makefile golden reference for the embedded example:
+   [stm32/nucleo-f746zg-baremetal](stm32/nucleo-f746zg-baremetal)
+- An example must build on Windows, Mac and Ubuntu Linux systems
+- Assume that user installed tools according to https://mongoose.ws/tutorials/tools/
+- Makefile must not include any other make files
+- Use `CFLAGS` for system-specific compilation options
+- Use `CFLAGS_MONGOOSE` for mongoose-specific compilation options
+- Use `$(CFLAGS) $(CFLAGS_MONGOOSE) $(CFLAGS_EXTRA)` to compile
+- If external repository is required, download it on demand using git
+  shallow clone. See embedded example golden reference
+- Keep Makefile as short as possible, but verbose to understand it easily
+- Symlink files when required, like `mongoose.c`, `ca.pem`, etc. Make no copies
+- Example's README.md should contain only the title and the link to mongoose.ws

-# A complete device dashboard
-
-This example is a demonstration of how Mongoose Library could be integrated
-into an embedded device and provide a complete device dashboard with the
-following features:
-
- Multiple logins with different permissions (admin and user)
- Login screen for non-authenticated connections
- A [preact](https://preactjs.com/)-based dashboard with multiple pages
- Internal variables
- A form that changes those variables
- All changes are propagates to all connected clients
- Live log stream
- Live video stream
-
-
-In essence, this example is a combination of several other examples
-pulled together (multiple-logins, dashboard, live-log, video-stream).
-
-# Screenshots
-
-This is a login screen that prompts for user/password
-
-![](screenshots/login.png)
-
-# Main dashboard
-
-A main dashboard page shows internal data, live video stream, and a form
-
-![](screenshots/dashboard.png)
-
-A live log page shows live log stream coming from device

+# A complete device dashboard
+
+This example is a demonstration of how Mongoose Library could be integrated
+into an embedded device and provide a complete device dashboard with the
+following features:
+
+- Authentication: login-protected dashboard
+- Multiple logins with different permissions (admin and user)
+- Web UI is fully embedded into the server/firmware binary, and does not
+  need a filesystem to serve it. UI is resilient to FS problems
+- Administrators can change server settings
+- All changes are propagated to all connected clients
+- The device is connected to the external MQTT server
+- Logged in clients can send/receive messages via MQTT
+
+## Screenshots
+
+This is a login screen that prompts for user/password
+
+![](screenshots/login.webp)
+
+## Main dashboard
+
+The main dashboard page shows the interactive MQTT console
+
+![](screenshots/dashboard.webp)

+  provides both static and dynamic content.  Static files, like CSS/JS/HTML

+  <div><code>curl -u admin:pass0 ${devaddr}/api/config/get</code> </div>

+  <div><code>curl -u admin:pass0 ${devaddr}/api/message/send -d 'message=hello'</code> </div>
+
+  <p>
+  The device can send notifications to this dashboard at anytime. Notifications
+  are sent over WebSocket at URI <code>/api/watch</code> as JSON strings: <code>{"name": "..", "data": ...}</code>

+          Cesanta Software Ltd. is headquartered in Dublin, Republic of Ireland.
+        </p>
+        <p></p>
+        Our story roots back to 2004, when Mongoose Web Server Library development started. <br>
+
+        As Mongoose Web Server grew in popularity and matured over the following years, in 2013 Cesanta was established to continue its development and 
+        provide support to our valued customers.
+        </p>
+        <p>We are proud to have among our customers many <i>Fortune 500</i> companies as well as medium and small size businesses.
+          Security and quality of our solutions is a paramount for us and the fact that Mongoose Web Server is used by NASA aboard the International Space Station is 
+          the best confirmation to it.</p>
+          <p>Since 2013, Cesanta has expanded its product portfolio. We develop and distribute embedded software and hardware with focus on connected products and the Internet of Things.</p>

-# An example ESP32 application
-
-To build this application, follow these steps:
-
-1. Make sure you have Docker installed
-2. Clone whole mongoose repository on your machine:
-  ```sh
-  git clone --depth 1 https://github.com/cesanta/mongoose.git
-  ```
-3. Start command line or terminal, and go into the example's directory:
-  ```sh
-  cd mongoose/examples/esp32
-  ```
-4. Run `make`. This invokes a Docker-based build. A firmware will be built
-  in the `build/` directory:
-  ```sh
-  make
-  ```
-
-# Flashing built firmware
-
-If you have a real board to flash to, you can flash a built firmware.
-First, make sure to have `esptool.py` script installed on your workstation.
-Then, connect the board to your workstation and run the following command:
-
-```sh
-make flash COMPORT=YOUR_USB_PORT
-```
